TASTING: MACHINE.

Application filed. July 23,

This invention relates to coating applying apparatus.

This invention has utility when incorporated in a machine for applying coating, as of adhesive or paste, to strips of material, as wallpaper.

Referring to the drawings Fig. 1 is a side elevation of an embodiment of the invention as a wallpaper pasting machine;

Fig. 2 is a perspective view of the reservoir, well, or fountain for the paste supply;

Fig. 3 is a vertical section longitudinally through the fountain or well with the strip material and paste handling elements there- 1n;

Fig. 1 is a perspective view of the cutter or knife;

Fig. 5 is a plan View of the apparatus of Fig. 1, parts being broken away; and

Fig. 6 is an elevation of the opposite end of the device to the showing in Fig. 1, with the apparatus control open, parts being broken away.

Legs 1 may support housing 2 having therein receptacle 3 as a well or reservoir for adhesive or paste t normally maintained at a level considerably below dip portions 5 in the sides of the housing 2. This well or :15? reservoir 3 is a unit from which the rest of till.

the apparatus is readily removed so that this well may 7e conveniently cleansed, as well as for supply of material thereto. Further more, in the removal condition, the other elements of the machine are more readily accessible for cleaning up after use so that ad-' hesive may not dry therewith to detract from the proper operation of the machine.

Side plates 6, T, are connected by four bars 8 to maintain this structure as a rigid rectangular frame. Centrally of this frame and in its lower portion, is shaft 9 carrying roll 10. As the side plates 6, 7, are placed in the open top of the reservoir 3, these plates contact the upper curved portions of this reservoir above the level of the liquid 1 with the roll 10 extending downward therefrom not fully to the bottom of the res ervoir 8, but for partial submergence in this paste 1 in the .cservoir 3.

Plate 6 has fixed therein trunnion seat 11 in the inner end of trunnion 12 adjustable as to its inward distance by set screw 13 in collar 1 3 "red with the plate 6. This ad just. efthe tr i1. .l...e;a12 axially par 1924. Serial No. 72'S,621.

placing of the seat 11 at a desired distance inward from the end of the paste applying roll 10 with which this trunnion 12 is axially parallel.

The plate 7, opposing the plate 6, has slot 15 therein so that strip material supporting shaft 16 may have end 17 thereof adjacent flange 18 inserted in the seat 11, while opposing flange 19 is yieldably thrown by spring 20 against roll of strip material 21 and thus may yieldably adjust such roll of strip material axially as the spring 20 coacts with washer 22 in the shifting of the shaft 16 downward for aligning with the trunnion 12.

This strip material, as wallpaper 21, on the supporting means supply roll or siaft 16, when wrapped thereon with its back or paste receiving side outward, has such paste receiving side directed upward for are contact with the paste receiving or first roll. 10 as protruding beyond the width of this strip material not only toward the plate 6, but also toward the plate 7. In passing over this are contact portion, this strip material 21 may travel downward to have the paste coated portion away from rotary guide element or second roll 23 on shaft 21 as moun ed for rotation between the plates 6, 7

This shaft 24textends to ride free of slots 2:") in the plates (3, 7, but for hearing is directly supported in auxiliary plate sections 26 having hooks 27. These plate sections 28 are mounted on aligned hinge pins 28 for swinging as to the frame 6, 7, S.

The element 23 as fixedly mounted on the shaft 2 1 carries outside the plate 7 gear wheel. 29 in mesh with gear 30 fast on the shaft 9. The ratio between these gears 29, 30, is such that, in the lineal travel of the strip material 21 from the supporting means 19 as one guide about the element 23 as companion parallel guide for effecting are contact for the material 21 upon the roll 10, this t'avel of the strip material as to the roll 10 is at a slightly different rate than the lineal speed of the periphery of the roll 10. This driving of the roll 10 is directly effected by the pulling of the strip of material 21 about the guide element .3 for thereby causing the element 23 to act as a driver. This difference in travel rate between the paste applying roll 10 and the strip material 9 ssists in the unifo m spreadin elf ll an in lines-2r,

side ofthe strip material. The hookmounting 27 for the shaft 24 in the frame plates 26 is such that when such frame plates 26 are swung upward from the frame 6, i, b, on the pivots or hinges 28, the roller element 23 may be readily removed for cleansing.

Mounted on the hinge pins 28 by arms 31 is bar 32 parallel with thesha-ft 2a and, carrying wiper of fiber or woolen 33 of an extent "greater. than. the width of the strip-material: 21. Thiswiper 83 by its gravity fall upon the paste coated side of the material. tends to spread out such material into thin, smooth coat The thickness of this coat is conveniently and; readily adjusted by the speed or draw of the free end of the strip material as drawn-from the element 23. A rapid rate of drawing means that the coat-- ing of. paste will; be thicker than with a slower rate of drawing,

The paste applyingroll 10. wider than the stripmaterial 21V insures the applying te'rial arecludes an end slonine' of waste upon such roller 23- and' thereby keeps such paste from the front side of :he paper or strip. The wiper 83 accumulates the sur-' pl'us paste and as this wiper, not only longer than the elementbut of an extent greater than'thelength. of the strip material, this paste accumulation extends to, the portionof. the wiper; 33 beyond the width of the strip material.

Ends 34 of" the guide element 23 are countersunk thereby giving overhang provision for the rotary element 23.. Extending from this overhang region and below the ends of the wiper 33 is bulge 35 for receiving any dripping-of paste from the wiper 33 and directing suchdripping back into the; reser voir 3' as clear of the strip: material... This conical bulge 35 is mounted in fixed position with the roll 23 on the shaft 24.

This strip material 21 drawn from the rotary guide element 23, passes over bars 36, 37, as providing a slot or'seat thereliietween to way 39 as a shield over the roll 10 and the support 16. This shield is, as well as the bars 3.6, 37,. fixed with the plates 26.1 This shield 39 forms an initial way or table. 'The houshig 2 carries flange 40 which may be connected to sectional extension 451 6 .2. as a further: continuation of the way 89. upon which'the unpasted side of the strip material may rest drawnv through the pasting machine. The extent of this drawing of'the strip material for matching design at desired strip lengths may be checked by gage 42. carried by the way sections 4.1. 42. These sections 41, may be. mounted upon a paper hangers table 43. or be otherwise supported as may be found desirable in practice.

Then the desired length of material to the drawn out position on the gage with the matching factor has been taken into account, such withdrawal may be stopped. The pasted port-ions of the paper may be folded, against each other. On the hinge pins 28 adjacent the arms 31 is a pair of alims 4A carrying therebetween knife l5 having centering portion L6 herein shown as protruding symmetrically of the way for the strip material 21. The strip length as determined is severedby swing of the arms 44 so-that the knife 4:5 enters the slot or. seat 38in effecting a quick severing of the pasted length. back and further strips drawn. for cutting as the pasted material is allowed to soak up before-being applied to thewall. The point 46 of the knife 45 being mid-way of the width of the strip material, there no= tendency in the cutting of the material, to. shift it from one side-toward. the other of the machine. Accordingly, the central position as adjusted by the trunnion. 1-2 for the strip inaterial is a position maintained in the travel of the material from the machine i The device is one of simple construction capable of a speed of operation such; that over hand pastingthe capacity of work for the hanger may be increased fifty per cent.. l urthermore, the pasting is of a smoothness and uniformity tothepaper edge not attainable in hand pasting, andthere is, accordingly, utility in the superior character of the pasting as well as the speed of performing such herein.

From the foregoing it will be seen that in the operation of this machine for applying a coating of paste to wallpaper, it is not material whether or not the paper is untrimmed as to both sides, trimmed as to one side, or trimmed asto both sides, for the machine as operating hereunder is effective for applying over the entire surface and up to. the edge whether trimmed or not, a uniform coating of the adhesive. This means that whether on not the paper to be applied be lapped or abut, there is paste over. the entire surface applied to the well clear up to the edge. However, there is no slapping of the paste beyond the edge, under any circumstances. in the operation of the machine as disclosed,
